The CNG series high-pressure ball valve is a new-generation valve designed to meet industry standards and is suitable for high-frequency cycling applications. It serves as an opening and closing device in high-pressure pipelines and hydraulic high-pressure pipelines at various filling stations. The internal screw design of the high-pressure ball valve body increases the diameter by 60%, which effectively disperses pressure impact and enhances the contact area between the ball and the seat seal. The ball valve seat design provides back pressure under high pressure, reducing the ball deflection angle, and increases the sealing preload under low pressure to ensure stable valve operation. The main body is manufactured using high-pressure impact forging, enabling the valve to withstand pressures up to 500 Bar. The valve features fire protection and anti-static design, with fire protection design and testing in compliance with API 6FA and API 607 standards.

Product Features

Seat Packing: Made from Polyseal, which offers excellent high-pressure performance and can operate within a temperature range of -40°C to +100°C.
Anti-Corrosion Metal Protective Ring: A special design that prevents direct contact between gas and the valve body's sealing components, ensuring the ball valve's sealing effectiveness and preventing internal leakage.
Shock-Proof Design: Given the unique application in CNG transport trailers, which experience vibrations during operation, the O-ring at the ball valve joint is prone to damage, leading to potential leakage. Through meticulous research and design, a special anti-leakage protection scheme has been added to the original design. This enhancement ensures both anti-internal and anti-external leakage protection.
Full Bore Design: The high-pressure valve features a full bore design, matching the diameter of the ball hole. This ensures that the gas medium can pass through the ball without causing local closure, maintaining smooth flow and reducing pressure drop.
